The assembly of this item was very complex. The first step was to screw in two guide rails. The holes were only partially bored and it required extreme pressure to get it filled it. The concept of the assembly was to have everything loose fit until the end when it would be tightened. I ran into continual problems with parts slipping out of alignment. I'm not a good reader of the wordless "easy to assemble" directions -- the diagrams make it difficult to discern front from back and up from down. It would have been far easier to include some photos. You don't have to print it -- just direct people to the website where you have photos or videos! The final product ended up being slightly out of alignment. I just wasn't happy with the assembly or the final product.
